The circuit breaker assembly is a transmission structure for realizing circuit breaking of the circuit breaker.
As specific structure, divide closing subassembly includes: and the driving motor 14 supplies power to the automatic opening and closing through the driving motor 14. A reduction gear set is connected to a motor shaft of the driving motor 14, and a driving gear 17 is rotatably mounted in the first housing 11 for meshing with the reduction gear set. Still rotate in the first casing 11 and be equipped with: the tripping device comprises a tripping connecting rod 18 and a poking rod 19, wherein the tripping connecting rod 18 is used for linking the breaker assembly to perform switching-off or switching-on, and the poking rod 19 is used for a user to poke to drive the tripping connecting rod 18 to perform switching-off or switching-on. The poke rod 19 is also linked with the breaker assembly, namely one end of the poke rod 19 is rotatably connected to the moving end of the breaker assembly for opening and closing, so that the breaker assembly is driven to open and close during rotation.
In this embodiment, the driving gear 17 is formed with a complete tooth portion 171 having a complete wheel shape and a protruding tooth portion 172 protruding from the complete tooth portion 171, the protruding tooth portion 172 is engaged with the teeth formed by the tap lever 19, the end of the tap lever 19 is a fan shape, the fan-shaped surface of the fan-shaped end is formed with teeth engaged with the protruding tooth portion 172, and the number of teeth of the protruding tooth portion 172 is greater than the number of teeth of the end of the tap lever 19. The teeth formed by the full teeth 171 are the same size and correspond one-to-one to the teeth formed by the protruding teeth 172. Thus, the drive gear 17 can drive the tap lever 19 to rotate integrally, and automatic closing is realized. The driving gear 17 is in interference fit with the tripping link 18 through the protruding tooth part 172, and the rotation of the tripping link 18 can drive the circuit breaker assembly to move, so that automatic opening is realized.

The protruding tooth portion 172 drives the trip link 18 to rotate between the opening position and the closing position by abutting against the other end of the trip link 18, that is, when the protruding tooth portion 172 abuts against the other end of the trip link 18 and presses the other end of the trip link 18 to rotate downward, one end of the trip link 18 drives the breaker assembly to open, and when the protruding tooth portion 172 is disengaged from the other end of the trip link 18, the other end of the trip link 18 is tilted upward, that is, reversely rotates, and drives the breaker assembly to close. The circuit board 13 is provided with a switch-off stopping switch 20 and a switch-on stopping switch 21, and the switch-off stopping switch 20 and the switch-on stopping switch 21 are electrically connected to the driving motor 14. A first triggering protrusion 173 is formed on the driving gear 17, and the first triggering protrusion 173 is used for moving between triggering the stopping and opening switch 20 and triggering the stopping and closing switch 21, that is, the first triggering protrusion 173 triggers the stopping and opening switch 20 when the tripping link 18 rotates to the opening position, at this time, the driving motor 14 stops, and triggers the stopping and closing switch 21 when the tripping link 18 rotates to the closing position, that is, the tripping link 18 is a driven member rotating adaptively, that is, the circuit breaker is at the closing position, that is, when the handle of the tap lever 19 is at the closing position, the first triggering protrusion 173 triggers the stopping and closing switch 21, and at this time, the stopping and closing switch 21 controls the driving motor 14 to stop.

When the driving gear 17 rotates until the first triggering protrusion 173 contacts the stop-and-close switch 21, the stop-and-close switch 21 controls the driving motor 14 to stop rotating. In the process, the tripping link 18 rotates to the corresponding switching-on position at the same time, the second triggering protrusion 181 triggers the switching-on state verification switch 22, and the circuit board 13 detects and verifies that the circuit breaker has been effectively switched on. In this state, the protruding tooth portion 172 of the driving gear 17 is disengaged from the end of the tap lever 19 without colliding against the trip link 18, so that the manual opening and the automatic opening of the driving motor 14 can be realized.
In the above-mentioned closing state, when a switching-off command is given to the driving motor 14, the driving motor 14 drives the driving gear 17 to continue to rotate clockwise, the protruding tooth portion 172 of the driving gear 17 moves to abut against the other end of the tripping link 18, and the tripping link is forced to rotate to the switching-off position, in this process, the circuit breaker assembly is driven to realize switching-off, and at this time, the second triggering protrusion 181 is no longer in contact with the closing state verification switch 22. When the first triggering protrusion 173 contacts the stopping opening switch 20, the stopping opening switch 20 controls the driving motor 14 to stop rotating clockwise and controls the driving motor 14 to rotate counterclockwise, and when the first triggering protrusion 173 contacts the stopping closing switch 21, the stopping opening switch stops, and the opening process ends. In this state, the protruding tooth portion 172 of the driving gear 17 does not abut against the trip link 18, and does not contact with the teeth of the end portion of the tap lever 19, and two closing modes, i.e., manual closing and automatic closing, can be realized.
